PWHT involves heating a welded component to a specific temperature below its transformation range, holding it, and cooling it uniformly. It is performed to relieve residual stresses induced by welding, improve ductility, and reduce hardness to prevent environmental cracking.
Features a knuckle radius and a crown radius. It is easier to form and cheaper than ellipsoidal heads but requires greater thickness to withstand the same design pressure.
ASME Section VIII (Div 1 vs. Div 2). Understand why Div 2 allows for higher allowable stress (and thus thinner walls) through more rigorous analysis. static equipment interview questions
An annular plate is a thickened ring of bottom plates located under the shell-to-bottom junction. Purpose:
Impingement protection is a plate or baffle placed directly below the shell-side inlet nozzle. It prevents high-velocity fluid entering the shell from eroding or causing vibration damage to the upper rows of the tube bundle. TEMA requires impingement protection when the entrance kinetic energy (
The industry standard for economic high-pressure applications. It offers a great balance between structural strength and manufacturing cost. To help you prepare further, I can provide more details
15. Choose the right NDT method for detecting: Surface Defects vs. Volumetric (Internal) Defects.
What is the difference between a 2:1 Ellipsoidal head and a Torispherical head?
What are the primary loads considered under ASME Section VIII, Div. 1, UG-22? Features a knuckle radius and a crown radius
Higher engineering cost; lower material cost for high-pressure applications. Generally used up to 3,000 psi. Can be used for much higher pressures. Pressure Vessel Design & Components
is identified by its exact Outside Diameter (OD) and wall thickness (often in Birmingham Wire Gauge, or BWG). It is primarily used in heat transfer applications like heat exchangers and boilers.
For a static equipment engineer interview, questions typically range from core mechanical design principles to specific industry codes like ASME and API. Core Technical Concepts Pressure Vessels & Shell Design
4. What is the difference between Design Pressure, Operating Pressure, and MAWP?
Corrosion driven by sulfur compounds at elevated temperatures (typically above 260°C).
